Texas Rangers ballyhooed right-hander Kumar Rocker made his major-league debut on Thursday night against the Seattle Mariners and turned in a strong and at times dominant outing. Rocker's line for the night:

“This is why he’s here,” Rangers manager Bruce Bochy would say later Thursday after a 5-4 comeback win over Seattle in Rocker’s debut. “I don’t think we had to learn anything. I think we knew he was ready. It was something we thought he could handle. This was a great start for him, especially how he handled himself in the first inning.”
